Glad to see this post. I have a similar problem. My WK tailgate hits my garage door when open so I’ve installed some rubber on the garage door so not scratch the WK tailgate. I’m concerned too with the WK2 Overland automatic tailgate hitting my garage door. I wonder what the automatic tailgate will do when it hits something? I hope it just stops.

Yep, I've been through this already. And the answer for this is so simple, that it kind of annoys me that Jeep engineers didn't think of it or atleast incorporate it into the design. On the Mercedes Benz ML, theres the button on your remote just like Jeep, and theres a huge red button on the lift gate as well. As it's opening, you can hit that button at any time and it will stop the gate and hold it there. Any button you hit to restart the gate will close it from that point. So it never matters what your over head clearance is as you can stop the gate when ever you want. It seems the GC is either opening all the way or closing all the way with no in betweens. But, the GC has the flip open glass, and the Mercedes doesn't. I've often wished I had the glass open ability to reach in there and grab something quick rather than open the entire lift gate. So I consider it a trade off.

Ummmm....it will probably break the plastic spoiler on the top before stopping. Was a HUGE issue for me in my condo parking garage...a water main lowers the height since it runs right through the middle front to back of my parking space. I just knew I'd hit the automatic lift gate someday and crack that sucker....soooo fortunately for me I was able to negotiate a cross assignment of parking spaces with another condo owner so I could get a parking space where it isn't an issue. If the ceiling is low then the spoiler may hit first (depends on how low) resulting in $$$ damages.
